`29+14/7 = 29 + 2 = 31`
` 15/24+17/8+9/12 = 5/8 + 17/8 + 3/4 = 22/8 + 3/4 = 22/8 + 6/8 =28/8 = 7/2`
`29+14/7=29+(14:7)/(7:7)=29+2/1=29+2=31`
`15/24+17/8+9/12=(15:3)/(24:3)+17/8+(9:3)/(12:3)=5/9+17/8+3/4=(5+17)/8+(3xx2)/(4xx2)=(5+17)/8+6/8=22/8+6/8=(22+6)/8=28/8=(28:4)/(8:4)=7/2`
\(29+\dfrac{14}{7}=29+2=31\)
\(\dfrac{15}{24}+\dfrac{17}{8}+\dfrac{9}{12}=\dfrac{15}{24}+\dfrac{51}{24}+\dfrac{18}{24}=\dfrac{84}{24}=\dfrac{7}{2}\)
